while I agree with the 2nd paragraph of the email Paul wrote, I believe that a small clarification should be made on the 1st paragraph. In x86, the NX bit can be emulated. Emulating the NX bit causes certain processors to fail to boot, although we are talking K6s/PentiumMMX era CPUs IIRC. Thus for all intents and purposes, NX-bit can be reliably emulated in modern x86 CPUs.
I think it's present and available for PAE memory addressing in all modern x86 CPUs. And yes, some kernels are able to emulate it in 32-bit modes as well. I think this illustrates my point (and yours) that exploitability of a vulnerability across platforms is about nuance. And it's additionally safe to say that exploitability has changed significantly in the last 5 years both within and across all modern platforms.
